Thrombus in hypoplastic aorta: An uncommon cause of acute myocardial infarction.

A coronary artery embolism is an uncommon non-atherosclerotic cause of acute myocardial infarction. We present a case of coronary artery embolism in a patient with past history of hypoplastic left heart syndrome that was initially palliated via a modified Blalock-Taussig shunt followed by a Fontan anastomosis and Damus-Kaye-Stansel type anastomosis of the pulmonary valve to the ascending hypoplastic aorta. In this case we demonstrate usefulness of cardiac CT to delineate the patient's complex anatomy, identify the presence and etiology of a thromboembolic event, as well as assess for appropriate response to anticoagulation therapy.
